Abstract
An apparatus and method for achieving power saving for a portable device in a wireless network for transmitting audio/video (A/V) data is disclosed. An optimal transmit power level is selected by transmitting multiple probe messages by a portable device at increasing transmit power levels until a response to one of the probe messages is received within a preset allowed response time. A relay node is selected by a portable device for receiving compressed A/V data, uncompressing the compressed A/V data, and transmitting the uncompressed A/V data to an intended receiver.
